Monthly Meeting, Monday, January 20, 2020 A Tale of Two Floras: Botanical Adventures at Home and Abroad with Evan Meyer Evan Meyer is the Assistant Director of the UCLA Mildred E. Mathias Botanical Garden, a diverse urban oasis in West Los Angeles. Prior to that he managed the Seed Conservation Program at Rancho Santa Ana Botanical Garden. California is globally renowned for its fantastic displays of annuals, sweeping landscapes of drought adapted shrubs and charismatic trees. The flora of western South Africa is equally famous, containing an incredible diversity of flowering shrubs, succulents, and bulbs. Join Evan as he shares stories of his travels throughout California and a recent expedition to the Western Cape of South Africa. He will compare these two remarkable parts of the world and describe how plants make the journey from wild landscapes to gardens.

Monthly Meeting, Monday, February 17, 2020 A Botanical Journey from Central Asia to the Middle East with Ori Fragman-Sapir Some of the most striking flower bulbs, as well as blooming trees and other plants, grow in steppes and other arid habitats: Central Asia (Tajikistan and Uzbekistan), the Caucasus (Armenia, Georgia, and Azerbaijan), Turkey, and the Holy Land (Israel to Jordan). These plants show magnificent adaptations to droughts, and many have potential for cultivation.

GOT PLANTS?

Each month we host a lively discussion about plants brought in by our members. They may be well grown specimens, unusual discoveries, or plants with attributes not known by the mainstream. If you are interested in participating, bring in a plant to show. You are also welcome to donate this plant afterwards to the plant drawing.

Donate Your Extras to Our Monthly Plant Drawing Did you sow too many seeds, root too many cuttings, or need to divide some plants that have gotten too big for your garden? Consider donating these extras to our monthly drawing at our next meeting.
